Hi,

Thanks for the reply.......

Can you explain me briefly...please.

Please tell me what exactly PTR record must be needed/added

to work correctly.

On the sendmail and internet server :

my lan ip = 192.168.1.10

external ip = 202.144.1.37

my registered domain = xyz.com(say)

my internal domain = abc.xyz.com
